Replace dead upstream images with custom build services; add retry logic

dtagdevsec/mailoney and dtagdevsec/elasticpot are unavailable on Docker Hub
("manifest unknown"), causing the entire deployment to abort and cascade-
interrupt all other image pulls.

- Convert smtp and elasticsearch to build services with custom Python
  honeypots: smtp emulates Postfix ESMTP (EHLO/AUTH/MAIL/RCPT logging),
  elasticsearch emulates ES 7.17 HTTP API (logs recon probes like /_cat/,
  /_cluster/, /_nodes/, /_security/)
- Both use ARG BASE_IMAGE so they participate in per-decky distro variation
- Add _compose_with_retry() to deployer: 3 attempts with exponential backoff
  (5s → 10s → 20s) for transient network failures; permanent errors
  ("manifest unknown", "pull access denied") are detected and not retried
- Update test_services.py and test_composer.py: smtp/elasticsearch moved
  from UPSTREAM_SERVICES to BUILD_SERVICES (314 tests passing)
